Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coffee maker that automatically manufactures regular coffee, and particularly to a coffee maker that securely fixes a filter cup and can be easily attached and detached.

[0002]

[Prior art]

 For regular coffee extraction, the drip type is often used because it is easy to obtain good taste and flavor and easy to handle. However, in the drip method, after boiling the water by boiling it, the hot water is gradually poured into the coffee powder in the paper filter (or the funnel filter) held in the filter cup to extract and filter the coffee liquid. There is a drawback that it is necessary to drop it on a container or the like, which is troublesome.

Therefore, conventionally, various coffee makers have been proposed that automatically extract and filter coffee liquid from boiling water by setting coffee powder and water in the apparatus body. For example, in Japanese Examined Patent Publication No. 60-9442 and Japanese Examined Patent Publication No. 2-32888, a filter cup holding a paper filter and a coffee container are installed in the main body of the apparatus, and the paper filter is placed from above the main body of the apparatus. It describes a method of pouring hot water intermittently into the coffee powder inside. However, in these coffee makers, because the filter cup is stacked on the coffee container, when changing the paper filter and coffee powder, or when transferring the coffee liquid in the coffee container to another cup, etc. In this case, the filter cup and the coffee container had to be temporarily removed from the main body of the apparatus, which was inconvenient to handle.

As a solution to such a problem, Japanese Patent Publication No. 57-11628 and Japanese Utility Model Publication No. 3-17795 disclose a filter cup which is horizontally rotated under the hot water supply port of the apparatus body. The one with is attached is described. In these coffee makers, the paper filter and the coffee powder can be easily replaced by rotating the filter cup with respect to the main body of the device. In addition, it is possible to remove the coffee container alone, which makes it extremely easy to handle.

By the way, in the latter coffee maker, after the extraction of the coffee liquid, the filter cup is swiveled with respect to the apparatus main body, and the used coffee grounds are removed together with the paper filter. However, this causes the coffee liquid to remain attached to the inner surface of the filter cup, so a structure that allows the filter cup to be removed and cleaned is desirable. Also, for a while after the coffee liquid is extracted, drops of coffee liquid fall from the bottom of the filter cup. Therefore, in order to prevent the device body and its surroundings from being contaminated by drops of coffee liquid, it is desirable to have a structure in which the bottom of the filter cup is automatically closed when the filter cup is swung or when the coffee container is removed.

6 and 7 show a coffee maker equipped with a detachable filter cup, which has a door 2 which rotates around a vertical axis (not shown) on the upper part of a substantially U-shaped device body 1. The filter cup 3 is provided so that the filter cup 3 can be detachably mounted in the door 2. A drop prevention valve 6 composed of a valve body 4 and a coil spring 5 is attached to the bottom of the filter cup 3, and opens when the valve body 4 moves upward. After setting the coffee container 7 in the apparatus main body 1, the filter cup 3 containing the paper filter 8 and the coffee powder 9 is fitted into the storage portion 10 of the door 2. Next, when the door 2 is swiveled and closed, as shown in FIG. 7, the valve body 4 of the drop prevention valve 6 is pushed by the lid 11 of the coffee container 7 and rises. At this time, since the coil spring 5 is compressed, the filter cup 3 is biased upward. Therefore, the door 2 is formed with the claws 12 at two places, and locks the filter cup 3 to prevent it from rising.

[0007]

[Problems to be solved by the device]

 The coffee maker with the removable filter cup described above also had the following problems.

In this coffee maker, the lifting of the filter cup 3 is prevented by the claws 12, but when the filter cup 3 is removed, the claws 12 become an obstacle, so the work was not easy. Further, since the claws 12 are configured to press the upper edge of the filter cup 3, a predetermined gap is required between the storage portion 10 of the door 2 and the filter cup 3 in consideration of mounting, so that the filter cup 3 can be securely attached. Could not perform positioning. Further, when the door 2 is vigorously closed, the filter cup 3 may come off the claw 12 and float up, causing the drop prevention valve 6 to close.

Therefore, an object of the present invention is to provide a coffee maker that solves the problems of the above-mentioned conventional techniques, facilitates attachment / detachment of the filter cup, and ensures the operation of the drop prevention valve.

[0010]

[Means for Solving the Problems]

 In order to achieve the above object, the coffee maker of the present invention comprises a device main body that heats water and causes it to flow down as hot water from a hot water supply port horizontally extended at the upper end, and a horizontal direction at the bottom of the hot water supply port of the device main body. A pivotally mounted door, a filter cup housed in the door for receiving hot water from the hot water supply port, and a drop prevention valve provided at the bottom of the filter cup that is biased from below to open. A coffee maker having a coffee container for storing coffee liquid dripping from the opening of the drop prevention valve, which is arranged at a lower portion of the filter cup, and a pressing portion for pressing the filter cup downward to the device body. Is formed.

[0011]

[Action]

 According to the present invention, when the filter cup is dropped into the storage part of the door and the door is closed, the filter cup is pressed downward by the pressing part of the main body of the device, and the drop prevention valve which is in contact with the lid of the coffee container opens. To do.
